How do we know that Jesus laid down His life for His sheep?

In John 10:15, Jesus states, 'I lay down my life for the sheep,' which is a profound declaration of His sacrificial love and purpose. This provision was made specifically for those the Father has given Him, the elect. Such an act demonstrates that His sacrifice was not a general or indiscriminate act, but rather a deliberate work intended for those who belong to Him. According to His divine plan, He bore the punishment for their sins, fulfilling God's justice while offering redemption to His chosen. This truth is foundational to understanding Christ’s role as a mediator and the assurance of salvation for His people.
